We get this information from what happened last year. Their website is not upto date with a lot of things. For eg, the submission deadline for MFE application is 5th Jan and 4th Jan at 2 different places, however, in reality there's no application deadline. I wouldn't rely much on the website information.
The interviews last year were over by about I think 16/18 Feb. This year it has been an extra week. Results were out starting 6th Mar last year (first round of results). First round this year could still be out next week.
